#1 is a neat concept, and might work in full color. But it took me quite a bit of staring to realize I was looking at two halves of two characters. At the smaller size, it looked like one weird-looking character, and the first impression I got was that it was a bored dog.

#2 is a mess.

#4 is cute, but it doesn't strike me as iconic really, and I see none of that struggle-for-honey concept in it. It's just a cute scene.

#3 is the most eye-catching to me. There's a lot of action in the honey splash and personality in the character's face.

Maybe even take the face/off concept from #1, colorize it, give each half a contrasting facial expression (right now both characters look equally apathetic), and put that on top of the honey splash from #3.

#3 is still the most iconic. It's recognizable at the smallest size of any of the 5, and the composition is simple and effective. There's just a little bit too much going on in the other four for me to vote for any of them.

#3 is obviously the best, but you need to shrink it down and look at it at iOS icon size. There is perhaps too much detail in the image for the bear to stand out as well as you'd like. I think he could be a bit bigger in proportion, and he's also too dark.
